What is Git?

Git is a version control tool used to manage and track changes in source code during software development. It helps developers collaborate, keep track of changes, and revert to previous versions if necessary.

Key Points:

  • Version Control Tool: Git keeps track of all changes made to your code.
  • For Source Code: It is specifically designed to manage source code for software projects.

Example: Imagine you are writing a book with a group of authors. Each author makes changes to different parts of the book. Git helps you keep track of who made what changes, and when, so you can review and combine everyone’s work efficiently.
